Patent number: 8640732Abstract: A two-stage regulator having a piston situated in a first stage for substantially reducing high pressures introduced into the regulator. The reduced pressure is exerted against the second stage that includes a plunger-actuated diaphragm that urges an actuator to open a ball valve at a selected pressure to allow fluid to flow out of the regulator at a desired reduced pressure.Type: GrantFiled: December 31, 2011Date of Patent: February 4, 2014Assignee: The Paul R. Beswick 2008 Irrevocable TrustInventors: Paul R. Beswick, Gary A. Treadwell

Patent number: 8448662Abstract: Two-stage and three-stage regulators having a piston situated in a first stage for substantially reducing high pressures introduced into the regulator. The reduced pressure from the first stage is exerted against a second-stage valve in a two-stage embodiment, and against an additional third-stage valve in a three-stage embodiment, each valve of which includes a plunger-actuated diaphragm that urges an actuator to open a ball valve at a selected pressure to allow fluid to flow out of the regulator at a desired and much-reduced pressure.Type: GrantFiled: June 9, 2010Date of Patent: May 28, 2013Assignee: The Paul R. Beswick 2008 Revocable TrustInventors: Paul R. Beswick, Gary A. Treadwell

Patent number: 7131459Abstract: A multi-port valve is disclosed having a ball bearing support system for a stator/rotor/valve stem assembly within a valve housing. Slipper seals or alternatively, poppet seals, connect a plurality of apertures situated in the rotor and a plurality of apertures situated in the adjoining stator so that a common central fluid receiving channel of the stator can be connected to a peripheral fluid delivery channel of the stator via a transfer channel in the rotor. The valve assembly provides a durable, virtually leak-proof system for delivery of a variety of fluids through the same delivery channel.Type: GrantFiled: June 2, 2003Date of Patent: November 7, 2006Assignee: Beswick Engineering, Inc.Inventors: Paul R. Beswick, Gary A. Treadwell

Patent number: 7114700Abstract: A valve for controlling the rate of fluid flow therethrough by rotating a rotor about a spindle having an inlet bore in communication with an eccentrically oriented o-ring set into an eccentrically oriented slot formed in the rotor. The perimeter of the eccentric slot is modified to provide customized unique fluid flow response curves.Type: GrantFiled: September 3, 2004Date of Patent: October 3, 2006Assignee: Beswick EngineeringInventors: Paul R. Beswick, Gary A. Treadwell

Patent number: 6314980Abstract: A pressure compensating flow control device is disclosed which has a needle valve/spring assembly as a reference restriction which is in axial alignment with a reducing valve situated in a housing of the device. A piston and piston rod is provided in axial alignment with the needle valve and reducing valve to provide compensation for alterations to pressure differential about the piston. The piston rod has an internal channel to allow for fluid communication between inlet and outlet chambers and to allow for passive control of pressure differential. The device provides pressure control for low fluid flows and low pressures.Type: GrantFiled: September 20, 2000Date of Patent: November 13, 2001Inventors: Paul R. Beswick, Gary Treadwell

Patent number: 4922805Abstract: A fluid actuated cylinder is provided having a piston and piston rod combination disposed in a tubular casing having a nose end and tail end. The piston is disposed on the piston rod spaced from both ends of the rod, the outer end extending through a bearing disposed at the nose end of the casing, and a unitary member which is employed to close the tail end of the casing is provided with a bearing for supporting the inner end of the piston rod.Type: GrantFiled: September 14, 1988Date of Patent: May 8, 1990Inventor: Paul R. Beswick

Patent number: 4037623Abstract: A sleeve valve having control of the rate of fluid flow therethrough by rotation of an outer sleeve is disclosed. Fluid flows in through a longitudinal bore in a valve body, then outward through one or more radial apertures extending outward from the longitudinal bore. An O-ring which is mounted eccentrically within a sleeve positioned around the valve body covers the radial aperture to an amount depending upon the angular position of the sleeve with respect to the valve body. The invention encompasses both flow control and metering valves. A linear or other desired relationship between angular position of the sleeve with respect to the valve body versus flow rate of fluid through the valve may be achieved.Type: GrantFiled: January 8, 1976Date of Patent: July 26, 1977Inventor: Paul R. Beswick

Patent number: 4013239Abstract: A continuous loop tape cassette with a rotating tape coil carried by a flanged, reverse e-shaped hub in fixed radial angular relation to the base of the cassette. A tape receiving arc portion of the hub has a radius sufficiently great relative to the spring modulus of the tape to prevent binding. The arc portion is undercut to contain the tape.Type: GrantFiled: April 14, 1975Date of Patent: March 22, 1977Assignee: Micro Communications CorporationInventors: Paul R. Beswick, Paul W. Berton, Charles F. Ganem, Clark E. Johnson, Jr.
